METHOD OF MAKING COMPOSITION HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 746,143, dated December8, 1903- l Application filed May 21, 1902.

To all whom; it may coitcern:

Be it known thatI, GEORGE J. PEAOOCK, of Pittsburg, Allegheny county,Pennsylvania, have invented a new and useful Method of MakingComposition Horseshoes, of which the following is a full, clear, andexact description, reference being bad to the accompanying drawings,forming part of this specification, in which Figure l is a perspectiveView showing the pile of fabric layers from which the blank is cut. thecut blanks, and Fig. 3 is a perspective view of the finished shoe withone end partly broken away to show the structure.

My invention relates to the manufacture of 'horseshoes formed of fabriclayers, and is designed to provide animproved method whereby a durable,strong, and simple shoe, composed mainly of fabric may be obtained.

In carrying out myprocess I coat layers of fabric, preferably heavy duckor canvas, on one or both sides witha thinlayer of gummy material,preferably composed of a mixture of ground duck or fabric and rubber.This thin layer may be applied by passing the fabric through acaleudering-machine, which will applya thin coating of the mixed rubberand ground duck or fabric. After a suitable number of layers of duck arethus treated they are piled up over each other, making a 1 pile of, say,one and one-fourth inches in thickness. I show such a pile of layers at2 in Fig. 1. This pile is then placed under a press having suitablecutting-dies, and a horseshoe-blank of the desired form, such asshown'at 3 in Fig. 2, is cut by the dies passing through the pile oflayers. I prefer to provide the shoe with a metallic piece or toeiron,and if this is done a recess is cut in the blank, preferably at the sametime that the blank is formed, as indicated at 4 in Fig. 2.

In Fig. 3 I show such a toe-iron 5, which is.

thinner than the shoe and is secured in a recess having smaller undercutrecesses which receive dovetailed lugs 6 on the iron. The

blank, which is of substantially the outline of but is much thickerthanthe finished shoe, is then placed in a socket-mold, together with themetal toe-iron or part, if such is used. A heavy pressure is thenapplied to the mold,

preferably by means of a hydraulic cylinder or cylinders, to stronglycompress the blank. The blank is vulcanized while retained under thispressure in the mold by heating the dies. The mold is then opened andthe finished shoe, such as shown in Fig. 3, is removed. The shoe thusformed is composed principally of the duck or other woven fabric. Thebinding layers serve to unite the fabric layers together, and as thelayers are united by the binder and compacted and vulcanized under heavypressure they are not liable to separate or pull apart in service. Theshoe is ordinarily formed offrom twenty to twenty-five layers of heavyduck, the layers being parallelwith the wearing-face,enough rubber beingused to give proper vulcanizing.

The advantages of my process will be apparent to those skilled in theart. The steps are few in number andeasily carried out at a low cost.The shoe may be easily adapted to different-shape hoofs and owing to itsconsisting mainly off-abri'c is found to wear longer than an iron shoe.The pieces or scraps resulting from cutting the blanks from the pile areutilized by grinding themup and mixing with the rubber or other bindertoform the thin layers between thefabrics.

Metallic parts may be appliedto the shoe either by placing them in themold and compressing the shoe in contact with them to firmly embed themetal or by applying them to the shoe after the compression ofvulcanizing, and many variations may be made in the particular fabricused, the composition of the binder, the shape of the shoe, &c., withoutdeparting from my invention.
